Imo there's not really that much difference between the beginning of the game and now. All he really did was add the rewrite the prologue slightly, add mc's aunt(by marriage), alice's mom and the blacksmith's daughter as love interest but as of 5.9 neither had any flags to get on their routes in the first place. Aside from that the only other difference is that he introduced a third alterntive choice to some of the intimidate/persuade choices, have Captain blackheart give the mc a lore dump on the circles of hell. Then add a tiny tiny bit more detail when the king is giving a lore dump on the other continents. If you want to see some of the new lore I guess it's worth it, but imo a restart isn't really necessary.
